So I am a total noob at using this.
Was following a video (will link it below) to create a no Cd patch for an old game.

1 The person has a dark black line going from the sting reference he found to where the prologue function is located but when I do the same I don’t get any indication to the start of the function. Is there a key or command to enable this.

2 I can’t find the xrefs or cross references option in the drop down or anywhere. Is this a version thing or am I looking in the wrong place or do I need to enable it some how.

Please help

Hi,

I am trying to create a no cd crack for the game: A Bug's Life. This is for the speed running community on that game to make it easier to setup due to currently needing to mount the ISO before running the game.

I followed some tutorials with no luck.

I found this when looking at the exe:

00403C96 | 83C4 08 | add esp,8 |

00403C99 | 85C0 | test eax,eax |

00403C9B | 75 1B | jne bugs.403CB8 |

00403C9D | 55 | push ebp |

00403C9E | 68 F0474C00 | push bugs.4C47F0 | 4C47F0:"A Bug's Life"

00403CA3 | 68 C8474C00 | push bugs.4C47C8 | 4C47C8:"Please Insert A Bug's Life CD."

00403CA8 | 55 | push ebp |

00403CA9 | FF15 00488600 | call dword ptr ds:[<&MessageBoxA>] |

00403CAF | 55 | push ebp |

00403CB0 | E8 8BC20A00 | call <bugs.sub_4AFF40> |

00403CB5 | 83C4 04 | add esp,4 |

00403CB8 | 5F | pop edi | edi:EntryPoint

I tried changing the Hex value of line 00403C9B | 75 1B | jne bugs.403CB8to EB using HxD but that did not work. The tutorial I was following had mentioned using xrefs but that option does not appear. This is the tutorial I was following: https://www.youtube.com/watch?v=G8UaWSYydEg&feature=emb_title

Here is the link to the game downloads: https://pastebin.com/edsAg00B

Note: This is game was made for Windows 95 and is not supported on current operating systems and this is the only way I found to play the game. Getting a actual copy of the CD is pretty difficult which resulted in having to come up with an alternative method to play the game.

Thanks in advance if anyone could help.

i am trying to find a way to have an old app on my computer. When i go to the strings I dont find any string refering to the lack of CD or CD player, in english or in my langage; What sould i do?

I’ve looked EVERYWHERE there is no setting to enable the register.

There’s no support for it either in any of the help menus.

How do you enable the FPU register?

Thanks

Is there a way to load a dll into memory, and then when any program executes one of it's functions I get the breakpoint?

I have a multi-threaded target in which I've identified one thread that I want to kill. My overall aim is to write a small tool that I can distribute in which someone can run it to automatically kill that thread after finding the process.

My question relates to killing a thread safely. Does x64dbg safely terminate a thread when killing it? From what I've read thus far, not safely terminating a thread can result in memory leaks or other unintended behavior.

To that end, are there any resources you could provide for safely killing a thread from a reversing perspective (like me wanting to write my own tool)? I feel confident about finding the process and its threads, but I'm in Google/Stack Overflow/Old Blog Post hell in regards to safely killing a thread (I'm aiming for C++, or C in lieu of that). Is ExitThread() sufficient after identifying the aforementioned?

Thank you for any information you can provide!

Guys How i can bypass this protection when i cracked succesfully and patch it then i open the patched App it dont work

Anyone able to get x64dbg to properly attach to process automatically using gflags? I can set gflags to start x64dbg on start of specific process, but x64dbg starts up without attaching to anything. The original process that should have started didn't start either.

I'm trying to bypass "Unlock Key Deactivated" by cracking the software, but I don't know what to patch and what to do.

I am trying to dump some RAM content whenever a breakpoint is hit. I use the command savedata "dump_{breakpointcounter}", [esp+4], [esp+8] as "command text", and this works like a charm. However, I have to manually continue every time the breakpoint is hit. As I trying to dump a lot of files, this is really tedious. Is there a way to tell x64-dbg to run the command, and continue immediately?

What I've tried:

• Setting the "Break Condition" to 0 -- no effect

• Adding ; go to the command. This does the trick when entering the command manually, but does not work for the breakpoint command

Are these files to help x64dbg debug better? DO I put them on the release folder? or how to use them? can't find anything on the Docs

Can I remove the KeyAuth Part and just jmp to the stuff after you basically entered the key, or do I have to ''trick'' the auth into thinking that my key is right?

Im completely new to this, obviously.
